Two interesting images posted only a few days apart showing two Soaring Dragon II UAVs each ... the first one at an for me unknown AB in the Northern Theater Command and the second image at Lingshui NAS at Hainan. pic.twitter.com/oSXzj8IZ9q

Brief but funny(?) origins of the nom.
Long, long ago and far, far away I was a telemetry analyst on Delta rockets. all new hires were really as it was a long and tedious task hand transcribing hex numbers into time-coded bit sensor data streams. I had an affinity for thinking in hex at the time so I was pretty prolific in turning over reams of the 132 column greenbar paper with edit marks on bad data.
The edits of a sensor losing it's timing became known as 'skids' so of course I immediately became known for leaving 'skidmarks'.

Miami-based Munilla Construction Management, which reportedly took on the bridge contract, was accused in a lawsuit from earlier this month of hiring "incompetent, inexperienced, unskilled or careless employees."

The failure was in the concrete itself and has nothing to do with the supports at each end. concrete crack / failure - possible at a 'seam' where the concrete was poured in segments - not sure what was happening within the concrete - but it was a transverse fracture - the key was looking at the support that is standing - by itself. it happened at the other end

No ideas yet on the Fla. ped bridge collapse, so don't ask. Pictures are too far away and without pertinent details. The responsibility weighs on everyone involved, I'm sure, and should. Prayers for the innocent victims and their families first
